Machining: Special related categories
 | Blanchard Grinding
Blanchard rotary surface grinding features large stock removal rates on flat surfaces. Ferrous materials are held on a magnetic chuck while the opposite surface is ground - one side is ground at a time. Non-ferrous materials can also be ground, but require special work holding arrangements - we call it magic.
The Blanchard will leave its trademark cross-hatched surface finish pattern, typically within a 32 - 125 RMS range, though higher finishes are possible.- Long or short runs.
- Ferrous or non-ferrous metals, annealed or hardened up to 62 RC.
- Flat, parallel, square and uniformity tolerances within 0.001 - 0.003 depending on size.
- Dimensional tolerance frequently requested is ±0.002.

High precision, horizontal reciprocating surface grinders are used to achieve flat, parallel and square surfaces on critical components. Machines are equipped with magnetic tables to hold ferrous parts, while special work-holding arrangements are required for non-ferrous parts. Component/part size can be controlled incrementally in ten-thousandths of inches.
Surface grinders will leave a smooth, linear surface finish, typically within a 16 - 32 RMS.- Flat, parallel, square and uniformity tolerances less than 0.001
- Dimensional tolerance frequently requested is ±0.0005
- Ferrous or non-ferrous metals, up to 62 RC
- Ceramic grain, borazon and diamond wheels available

Flat Honing is a type of double sided ′′fine grinding′′ where two opposed grinding wheels are used to remove stock from both faces of a flat part at the same time. Component/parts are held between the two wheels with carrier fixtures throughout the grinding cycle. Our Norton Hyprolaps and Peter-Wolters AC-470 are the method of choice on small, non-ferrous parts.
Flat Honing will deliver a high, random-pattern surface finish, typically in the 8 - 16 RMS range on most materials.- Long or short runs.
- Ferrous or non-ferrous metals, annealed or hardened to 62 RC.
- Flat and parallel results typically within 0.0002.
- Dimensional tolerance frequently requested is ±0.001.
- Surface finishes of 5 RMS can be achieved on some materials.

Abrasive waterjet cutting is a method of cutting shapes from any type of material using high pressure water and abrasive. Water is pressurized to 50,000 PSI using hydraulic intensification, and then forced through a small orifice in the cutting head. At the head, abrasive is added to the water, creating a cutting stream which exits the nozzle at 1.5 times the speed of sound. Through a combination of micro-erosion grinding and shearing action of the pressure, a narrow cross section of material is removed all the way through the thickness. The process is then controlled via computer. Any two dimensional shape from nearly any material is possible.
The resulting surface finish on the cut surfaces is far superior when compared to laser cut, torch cut or sawed surfaces. The process is non-evasive and does not work-harden the cut edges. Depending on material and dimensional tolerances desired, some sheet stock can be stacked for faster through-put.- Cuts virtually any material.
- Most cost effective when metal materials are under 1/2 inch thick.
- Accurately cut 2-dimensional geometries within ±0.010.
- Customer AutoCAD drawings can be retrieved via e-mail.
- Scanned images or free-hand drawings can be scaled and cut.
- We can produce AutoCAD drawings from your blue prints.

 | High Precision Blanking Service
High precision blanking is the process of creating a “machine-ready” batch of parts completed to the finished overall dimensions of a critical component. The critical component is typically completed via CNC machining in a subsequent operation. This process ensures that each blank is virtually identical across the entire batch. We process many blanks in a single machine loading, which is frequently much more cost effective than qualifying six sides on a CNC one piece at a time. As a result, the finish machining operation is faster and more cost effective, with a very high quality finished component coming off the CNC. |
 | Non-Ferrous and Refractory Metals
At Euclid Precision Grinding we use abrasives to shape specialty metals into essential components used in the semi-conductor, aerospace, medical and machine tool industries. In particular, our expertise with refractory metals like Molybdenum and Tungsten is well regarded internationally.
